4HOSE-COUPLINGV AND AUTOMATIC VALVE.

SPECIFICATION forming part of Letters Patent No. 711,771, dated October21, 1902.

Application filed May 16,1902.

To all whom it may concern:

Beit known that I, WILLIAM H. KELLER, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented anew and useful Improvement in Hose-Couplings andAutomatic Valves, of which the following is a specification.

My invention consists of an improvement in hose-couplings and automaticstop-valves wherein I provide means controlled by the operator foropening the valve and means for automatically closing the same.

It further consists in novel details of construction, all as will behereinafter fully set forth.

Figure 1 represents an elevation of a coupling embodying my invention.Fig. 2 represents a sectional view on line Fig. 1. Figs. 3, 4:, and 5represent perspective views of portions of thecoupling in .detachedposition. Fig. 6 represents a partial side elevation and partialsectional view of a portion of a coupling, showing the valve in openposition.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings, 1 designates a casing which is adapted toreceive a nipple 2, having the anged end 3 thereon and the passage 4therethrough, the inner end of said nipple being molded out, as at v5. Asuitable packing 6 is placed between the iiange 3 and the inner wall ofthe casing 1.

7 designates a mesh or screen, which is placed at the inner end of thenipple 2 and is adapted to catch dirt and other foreign substances thatmay enter with the motive Huid.

8 designates a spring, which is situated within the casing and bearsagainst the screen 7 at one side and against a valve 9 at the other end,said valve having a suitable portion 10 thereon, which is adapted tobear against the seat 11, which is carried by a nut 12, the latter beingscrewed or otherwise secured to the casing 1, said valve being providedwith suitable openings 13.

14 designates a pipe or-nipple, which is adapted to be secured to thenut 12, said nipple having the passage 15, which communicates with theopening 16 at the inner end of Serial No. 107,584. (No model.)

said nipple, which is also provided with a nut l'for operating the same.It is evident that said nipple 14 can be secured to a machine, tool, orhose, as may be desired, and ,that the inner end of said nipple isadapted 'to abut against the valve 9.

The operation is as follows: The nipple 2 being suitably connected witha hose and the motive Iiuid turned on at any suitable point, the samecan pass into said coupling, and as the valve 9 is properly seated andheld there by the spring 8 no uid can escape. In addition, the pressureof the motive fluid itself will assist in holding the valve seated. Whenit is desired to couple a hose or to secure the same to a machine ortool to operate the same, the nipple 14 is properly connected thereto,and the operator byturning the casing 1 causes the nipple to bearagainst the vvalve 9 and force thesame from its seat, whereby the motivefluid .will pass through the ports 13 in the valve and through opening16 and passage 15in the nipple 14 to the desired point. When it isdesired to stop the motive fluid by a reverse movement of the casing 1,the valve 9 is automatically seated, since the nipple 14 no longer bearsagainst the same, so that the motive liuid cannot pass through. l

It will,I be evident from the above that by 'flow of the motive fluidthrough the coupling can be adjusted according to requirements, sincethe valve can be moved more or less from its seat according torequirements.

It will be evident that various changes may be made by those skilled inthe art which will come within the scope of my invention, and I donot,therefore,desire to be limited in every instance to the exactconstruction herein shown and described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a hose-coupling, a casing, an inletpipe therefor, a valve-seatwithin said casing, a valve adapted to rest against said seat, a springinterposed between said valve and said inlet-pipe, and an outlet-pipe inthreaded engagement with said casing, whereby the rotation andlongitudinal movement of said cas- IOO ing relative to said outlet-pipecauses said valve to be unseated according to requirements.

2. In a hose-coupling, a casing, an inletpipe therefor, a strainerthrough which said inlet-pipe discharges, a valve-seat Within saidcasing, a valve adapted to rest against said seat, a spring interposedbetween said valve and said inlet-pipe, and an outlet-pipe in threadedengagement With said casing,where by the rotation and longitudinalmovement of said casing relative to said outlet-pipe causes said valveto be unseated according to requirements.

3. In a coupling, a valve, a seat therefor, means for holding said valveagainst said seat, devices capable of both rotary and longitudinalmovement controlled by the operator for moving the valve from said seat,and devices for retaining said valve in unseated position after the handof the operator is removed therefrom.

4. In a coupling, a casing, a valve therefor, a vspring holding saidvalve normally against its seat and a pipe having an opening thereinadaptedto force said valve from its seat, said casing being rotatablymounted on said pipe whereby the rotation and longitudinal movement ofsaid casing with respect to said pipe causes the latter to enter saidcasing and unseat said valve.

5. In a device of the character named, a casing, an inlet-pipe therefor,the latter having a flanged end within said casing, a valveseat'withinsaid casing, an apertnred valve adapted to rest against said seat, aspring interposed between said valve and iianged end, an outlet-pipehaving a slotted end adapted to contact with said valve, and meansWhereby the rotation and longitudinal movement of said casing relativeto said outlet-pipe will unseat said valve according to requirements.

6. In a device ofthe character named, a casing, an inlet-pipe having aflanged end located within said casing, a valve-seat within said casing,a valve consisting of a plate having portion adapted to contact withsaid seat, the outer portions of said valve having openingstherethrough, a spring intermediate said valve and fianged end, adischarge-pipe upon which said casing is rotatably mounted, an end ofsaid discharge-pipe being slotted and adapted to contact with saidvalve, and means whereby the rotation and longitudinal movement of saidcasing will cause the slotted end of said pipe to unseat said valve.

' 7. In a device of the character named, a casing, an'inlet-pipe havingaange thereon, said ange being contained Within said casing, apacking-ring interposed between the latter and said flan ge, a valvecontained Within said casing, a screen adapted to abut against saidiange, a spring interposed between said screen and valve, openings inthe outer portion of the latter, a nut in threaded engagement with saidcasing and adapted to serve as a valve-seat, and a nipple ordischargepipe in threaded engagement with said nut,

' said nipple having its end slotted and adapted to contact with saidvalveso that the latter will be unseated when said casing is rotatedupon said nipple.
